This bug is tagged needs-packaging which identifies it as a request for a new package in Ubuntu. As a part of the managing needs-packaging bug reports specification, https://wiki.ubuntu.com/QATeam/Specs/NeedsPackagingBugs, all needs-packaging bug reports have Wishlist importance. Subsequently, I'm setting this bug's status to Wishlist.

disk-manager is in the Ubuntu archive sync blacklist as a fix for bug 333596. You'll probably want to talk to Steve Langasek if you think the issues that led to its removal no longer apply. I'm setting this bug to incomplete waiting for a follow up about whether this is wanted in Ubuntu.

I removed the package and blacklisted it on request of an Ubuntu developer. If an Ubuntu developer says that the blacklist entry should be removed, the archive admins will certainly do so, but I'm not volunteering to be the Ubuntu developer to look into this. :)
